Influence in Operating Conditions on Fouling Resistance with PVDF Membranes within MBRs

The performance of membrane bioreactors (MBRs) is significantly impacted by the fouling resistance of the employed membranes. Polyvinylidene fluoride (PVDF) membranes are widely employed in MBR applications due to their positive properties such as high permeability and chemical resistance. Operating conditions play a vital role in determining the severity of fouling on PVDF membranes. Parameters like transmembrane pressure, feed flow rate, temperature, and pH can greatly affect the fouling resistance. High transmembrane pressures can increase membrane compaction and cake layer formation, leading to increased fouling. A low feed flow rate can result in increased contact time between the membrane surface and foulants, promoting adhesion and biofilm growth. Temperature and pH variations could also modify the properties of foulants and membrane surfaces, thereby influencing fouling resistance.
